Cosmic Multipoles in Galaxy Surveys II: Comparing Different Methods in Assessing the Cosmic Dipole
Vasudev Mittal, Oliver T. Oayda, Geraint F. Lewis
We present a comparative analysis of estimators and Bayesian methods for determining the number count dipole from cosmological surveys. The increase in discordance between the numb…
Cosmic Multipoles in Galaxy Surveys Part I: How Inferences Depend on Source Counts and Masks
Oliver T. Oayda, Vasudev Mittal, Geraint F. Lewis
We present a new approach to constructing and fitting dipoles and higher-order multipoles in synthetic galaxy samples over the sky. Within our Bayesian paradigm, we illustrate that…
A Bayesian approach to the cosmic dipole in radio galaxy surveys: Joint analysis of NVSS & RACS
Oliver T. Oayda, Vasudev Mittal, Geraint F. Lewis +1
We examine the sky distribution of radio galaxies in the NRAO VLA Sky Survey (NVSS) and the Rapid ASKAP Continuum Survey (RACS). Analyses of these samples have reported tension bet…
